Description

[Detailed description of the invention] This invention relates to a water sprinkler for a water circulation type automatic ice maker.

Normally, when ice is made from running water in a short period of time, the running water drops to a temperature of 0° C. or lower, and ice resembling cotton is instantaneously generated in the water circulation path due to some kind of impact.

This pure water clogs the starry part of the pump motor that circulates water, lowering the discharge pressure of the pump motor and stopping water sprinkling.

Then, when the pure water in the water circulation path begins to gradually dissolve due to the temperature inside the refrigerator, it gets stuck in the starry section of the pump motor, and the pure water also gradually dissolves.

At the same time, the discharge pressure of the pump motor also gradually increases while sending the pure water in the tank to the sprinkler.

However, conventionally, since the sprinkler 1 has a cylindrical structure as shown in FIGS. 1A and 1B, the upper surface a of the inner wall of the sprinkler and the plurality of sprinkler holes 2 are located close to each other. Pure water easily clogged watering hole 2.

Furthermore, since ice at approximately 0° C. is sent into the sprinkler 1, the pure water in the sprinkler hole 2 is difficult to melt.

Therefore, the water sprinkling holes 2 were clogged with pure water for a long time.

In general, when watering is stopped and then restarted, air is trapped inside the ice and cloudy water is formed. ing.

Therefore, in conventional water sprinklers, the sprinkler holes 2 remain clogged with pure water for a long time, resulting in cloudy water, and in severe cases, uneven ice can form.

Such ice is undesirable and looks unsanitary.

Simply increasing the diameter of the sprinkler in order to solve this drawback would result in the distance between the top surface a of the sprinkler and the watering hole 2 by the increased distance, but the volume of the sprinkler would increase and This required more ice-making water, and this increased amount required additional cooling to maintain the temperature at 0°C, resulting in a decrease in ice-making capacity.

The present invention has been devised to alleviate these drawbacks, and an object of the present invention is to provide a water sprinkler for an ice maker in which the water sprinkler holes are not clogged with pure water.

Next, the water sprinkler of the present invention will be explained in detail according to the drawings.

As shown in Figures 2A, 2B, 3A, and 3B, the water sprinkler 4 of the present invention has a pump connection part connected to a hose 6 of a pump that circulates ice-making water to an ice-making unit (not shown). 7
a water sprinkling pipe section 9 defining a central hole 8 through which ice-making water from the pump connection section 7 passes; and a plurality of water sprinkling holes 5 formed at the lower part of the water sprinkling pipe section through which the ice-making water in the water sprinkling pipe section is sprinkled to the ice-making section. It is equipped with

In FIGS. 2A and 2B, the central hole 8 of the water sprinkler pipe section 9 has an oval cross-sectional outline, and in FIGS. 3A and 3B, the central hole 8 has an oval cross-sectional outline. It is a pot-shaped hole.

However, the profile shape of the cross section of the central hole 8 is not limited to these two shapes, and may be any shape as long as it is a vertically long hole.

As shown in Figures 2A, 2B, 3A, and 3B, the conventional drawbacks can be improved by increasing the distance between the upper surface of the inner wall of the water sprinkler 4 and the plurality of water spray holes 5.

As described above, when the water sprinkling stops and water is about to be sprayed again, the pure water moves toward the water sprinkling hole 5.

However, in the sprinkler of the present invention, as shown in FIGS. 4A to 4, the distance between the upper surface of the inner wall of the sprinkler 4 and the sprinkler hole 5 is greater than that of the conventional sprinkler.

For this reason, the ice-making water sent from the hose 6 connected to the pump and the pure water 10 in the sprinkler 4 are separated by the buoyancy of the ice, and the pure water 10 is distributed along the upper surface of the inner wall of the sprinkler 4 to the tip of the sprinkler 4. move towards.

That is, the ice-making water and the pure water 10 move according to the progression order shown in FIG. 4A to FIG. 4D.

Therefore, since pure water does not pass through the water sprinkling holes 5, the water sprinkling holes 5 are not clogged with pure water.

The time it takes to transition from the state shown in FIG. 4A to the state shown in FIG. 4D is much shorter than in the past, and the time it takes for the water to be sprayed all at once and fall on the ice making section is also short.

Therefore, according to the sprinkler of the present invention, the sprinkler 5 is not half-clogged with pure water, and water is sprinkled all at once.
You can get ice with less cloudiness and no unevenness.

Then, the pure water at the tip of the water sprinkler is slowly melted by the temperature inside the ice maker and the water near 0°C, and ice making is completed.

The ice made in this way is of better quality and has better transparency than conventional ice.
